With the development of the instrumentation industry nowadays, the characteristic advantages of the metal tube float flowmeter (small pressure loss, large detection range, and easy use) have become a kind of flow measurement instrument commonly used in industrial automation process control. It can be used to measure liquids. The flow rate of gas and steam is particularly suitable for medium flow measurement with low flow rate and small flow rate. Therefore, we must pay attention to the installation to ensure the normal use of metal tube float flow meter and ensure its accuracy. Try to avoid direct sunlight and high temperature (≥65°C) to avoid reducing the capacity and life of the lithium battery. In order to ensure the normal operation of the metal rotor flowmeter and achieve the required measurement accuracy, the following points should generally be noted: 1. The metal rotor flow meter must be installed vertically on the non-vibrating pipeline. The fluid flows through the flow meter from bottom to top, and the verticality is better than 2°. The horizontal angle is better than 2° when installed horizontally, in order to facilitate maintenance and replace the flow. Meters, cleaning measuring pipes, metal pipe float flowmeters installed in the process line should be added with bypass and bypass valves. 2. The inlet of the metal tube float flowmeter shall have a straight pipe section with a length of more than 5 times the pipe diameter. The exit should have a 250mm straight section. 3. If the medium contains ferromagnetic material, install a magnetic filter; if the medium contains solid impurities, consider installing a filter between the valve and the straight pipe section. 4. When used for gas measurement, ensure that the pipeline pressure is not less than 5 times the pressure loss of the flow meter to make the float work stably. 5. When thermal insulation protection measures are required, if the temperature of the measured medium is higher than 220°C or the fluid temperature is too low, crystallization will occur easily. Jacket type should be used for cooling or insulation. 6. Pipe flanges, fasteners, gaskets and flow meter flanges are the same for the normal installation and operation of the meter. 7. Metal tube floater flowmeter faults usually occur when the device is just started. Because the pipe is not clean, the floater is stuck by solid particles. At this time, the pointer of the indicator stops at a position. At this time, the valves on both sides of the flowmeter should be closed first, then the upper flange should be removed, the float should be removed for cleaning, and then reinstalled. NOTICE Tighten the upper flange nuts for balanced tightening and gaskets. 8. The flange of the process line must be coaxial with the flowmeter flange and parallel to each other, in order to avoid deformation of the flowmeter caused by the pipe. Proper tube support to avoid pipe vibration and reduce the axial load of the flowmeter. The control valve in the measurement system should be installed downstream of the flowmeter. 9. At least 10cm around the installation, because the instrument is transmitting signals through magnetic coupling, in order to ensure the performance of the instrument, ferromagnetic substances are not allowed to exist. If the gas is directly discharged to the atmosphere at the outlet of the meter, the gas is measured at a specific pressure. The pressure drop will occur at the float and cause data distortion. If this is the working condition, a valve should be installed at the outlet of the instrument. 10. Be careful. Due to uneven pressure, when installing PTFE-lined instruments. PTFE will deform, so the flange nuts are evenly tightened symmetrically. 11. When installing, try to avoid direct sunlight on the display, with a liquid crystal display meter. In order to avoid reducing the life of the LCD. Metal tube floater flowmeter is an important type of flow meter nowadays, and now its development has been speeded up. Now Chengfeng Instrument has newly developed a third-generation metal tube floater flowmeter, which further improves the availability of metal tube floater flowmeters. Advantages, it has the following characteristics: one-time molding inside and outside the cone tube integrated type, solid and simple measurement tube without dead ends, the float can rotate easily blocked, the magnetic components are not affected by the magnetic field. Low pressure loss design, modular, intelligent, card-type indicator. The new ESK transmitter is synchronized with the international market! The introduction of advanced foreign computing software guarantees accurate calculations. Medium, viscosity, density, temperature, pressure multi-level correction.
